JOYTECH DMT-4760B Predictive Digital Thermometer

Warning

• Read instructions thoroughly before using digital thermometer.
• Choking Hazard: Thermometer cap and battery may be fatal if swallowed. Do not allow children to use this device without parental supervision.
• Do not use a thermometer in-ear. Designed use is for oral, rectal, and armpit (axilla) readings only.
• Do not place the thermometer battery near extreme heat as it may explode.
• Remove the battery from the device when not in operation for a long time.
• The use of temperature readings for self-diagnosis is dangerous. Consult your doctor for the interpretation of results. Self-diagnosis may lead to the worsening of existing disease conditions.
• Do not attempt measurements when the thermometer is wet as inaccurate readings may result.
• Do not bite the thermometer. Doing so may lead to breakage and/or injury.
• Do not attempt to disassemble or repair the thermometer. Doing so may result in inaccurate readings. After each use, disinfect the thermometer especially in case the device is used by more than one person. Do not force the thermometer into the rectum. Stop insertion and abort the measurement when pain is present. Failure to do so may lead to injury.
• Do not use a thermometer orally after being used rectally.
• For children who are two years old or younger, please do not use the devices orally.
• If the unit has been stored at temperatures over 41℉～104℉(5℃～40℃), leave it in 41℉～104℉ (5℃～40℃) ambient temperature for about 15 minutes before using it.

Indications For Use
The digital thermometers are intended to measure the human body temperature in regular
mode orally, rectally or under the arm. And the devices are reusable for clinical or home use on people of all ages, including children under 8 years old with adult supervision.

PLEASE READ CAREFULLY BEFORE USING
The predictive digital thermometer provides a quick and highly accurate reading of an individual’s body temperature. Predictive-read thermometers are quicker than actual read thermometer. Predictive read type thermometers display the temperature results in a short period of time which are equivalent to balance temperature after 5 minutes according to the particular algorithm. Therefore, users only need about 5 seconds to take the temperature readings. Due to measurement sites of predict thermometer are different, the reading time also may be different, but the actual time is usually between 5 and 10 seconds. (See below Figture 1)

SYMBOL EXPLANATION

SPECIFICATIONS

℃/℉ SWITCHABLE
Temperature readings are available in the Celsius or Fahrenheit scale (℃/℉; located in the upper right corner of LCD.) With the unit off, press and hold the On/Off Button for approximately 3 seconds to change the current setting.

MEMORY MODE

•  Power on the thermometer.
• During the last memory displays, press and hold the On/Off button until entering into Memory Mode.
• Press the button again to cycle check the last 10 memories
• Long press the On/Off button for 3 seconds to quit the memory mode.

SELECT MODE

1. Power on the thermometer.
2. During the mode displays, press and hold the On/Off button until mode flashing.
3. Press the button again to cycle through the four-mode options (see figure 3).
4.  When the desired mode displays on screen, wait for auto entering into measurement mode.

Bluetooth requirements

1. The Glucose Meter requires a Bluetooth device with Bluetooth 5.0.1 Android 6.0 or later IOS 10.0 or later.
2. And works with: iPhone , iPod, iPad. Android Phones and Tablets.
3. When you see the LCD display “ ” flashing, it means that the thermometer is waiting for Bluetooth connection, you only

FEVERLINE INDICATING TECHNOLOGY

At the completion of each measurement, the triangular arrow on the display will indicate different temperature ranges. Triangular arrow explain: For example:

DIRECTIONS

1. Please download and install the “JoyHealth” APP from the Website or APP Store (Such as Apple Store),before using this product. Then use your email account to register a new account and log in. Selection “thermometer” device,And turn on your phone’s Bluetooth.
2. Press the On/Off Button next to LCD display. A tone will sound as the screen shows(See Figure 4) , followed by last recorded temperature. After showing the mode of measurement(See Figure 3), the thermometer will enter into the testing mode(Oral/Underarm/Rectal mode see Figure 5 or Bath Mode see Figure 6).
3. Position thermometer in desired location (mouth, rectum, or armpit.)
4. Oral Mode: Place thermometer under tongue as indicated by“√” position shown in Figure 7. Close your mouth and breathe evenly through the nose to prevent the measurement from being influenced by inhaled/exhaled air.
5. Rectal Mode: Lubricate silver probe tip with petroleum jelly for easy insertion. Gently insert sensor approximately 1cm (less than 1/2 “) into rectum.
6. Underarm Mode: Wipe armpit dry. Place probe in armpit and keep arm pressed firmly at side. From a medical viewpoint, this method will always provide inaccurate readings, and should not be used if precise measurements are required.
7. Bath Mode: It will display Lo and then ℃ or ℉ is still flashing( ), then place probe tip into bath water.
8. Note: The accuracy of unit must be tested using water bath in bath mode. The three dashes (—) will flash sequentially throughout the testing process, and at the same time the “ ” are flashing(See Figure 8).When flashing stops an alarm will beep for approximately 10 seconds. The predictive measured reading will appear on the LCD simultaneously( ℉ see Figure 9).The measurement time of the oral/underarm/rectal mode varies with the individual, which are between 5 and 10 seconds.
9. :The minimum measurement time of Bath Mode until the signaling tone (beep) must be maintained without exception. The thermometer will enter into the Actual Measurement after 3 minutes except Bath Mode,At the same time you can hear two beeps as a cue ( The “ ” will disappear and the Actual measurement temperature display see Figure10), users can take the true body temperature at this time. Users can compare the predictive temperature result with true temperature result. In order to achieve better body temperature measurement result, recommend to keep the probe in mouth and rectum about 2 minutes, or in armpit about 5 minutes regardless of the beep sound and at least 30 seconds of measurement inter should be maintained.
10. To prolong battery life, press the On/Off Button to turn unit off after testing is complete. If no action is taken, the unit will automatically shut off after around10 minutes

CLEANING AND DISINFECTION

1. Immerse the thermometer probe in distilled water for at least 1 minute;
2.  Use a clean, soft cloth to wipe the thermometer down to remove any residue;
3. Repeat steps 1 and 2 for three times until no soil is seen with visual inspection after cleaning;
4. For thoroughly clean and disinfection, please use method A or B：
5. Method A(High-level disinfection): immerse the thermometer probe in 0.55% OPA(O-Phthaldehyde), such as CIDEX OPA, for at least 12 minutes under a temperature at 68℉;
6. Method B(Low-level disinfection): Using a clean soft cloth dipped in 70% medical alcohol, wipe the probe 3 times,at least one minute for each time.
7. Repeat steps 1 to 3 to remove OPA residuals;
8. Note1: Rectal use is not recommended for home use as OPA will not be readily available outside of a hospital. If rectal measurement is necessary, we strongly recommend high-level disinfection.
9. Note2: Please operate according to the manual of OPA for reference.
10. To prevent damage to the thermometer please note and observe the following:
11. Do not use benzene, paint thinner, gasoline or other strong solvents to clean the thermometer.
12. Do not attempt to disinfect the sensing probe (tip) of the thermometer by immersing in alcohol, OPA or in hot water (water over 122℉(50℃) for long time. -Do not use ultrasonic washing to clean the thermometer.
